Vapour Cloud, Elland

Established in 2013, Vapour is a cloud-first digital transformation specialist delivering secure voice, network and storage – such as a secure, automated appointment booking service for the NHS.

With £4m of investment under its belt, the firm led by ex-soldier Tim Mercer recently won its biggest single contract to date – a five-year £2m deal with Betfred – in a tender alongside BT and Cisco. On the lookout for more partners, the firm has £10m to fuel acquisitions over the next year.
